Interesting, ok does the USA and Australian 1979 f 250 3m3,have a different bore and stroke than the other 1979 models As mine is pointing more towards 55.89 bore with a shorter stroke than 54 x 54 as stated .

Sounds like someone built a short stroke motor for yours. Maybe same type of crank geometry as the TZR250, 56 mm bore and 5X stroke

Hi lots of really good detail about model difference, I have a 250C which is a German import with spiked wheels and disc front and back, my question is can I fit ally wheels from the later models with my discs etc. ?
